In 2010, National Geographic hired me to help them map out all of El Capitan's routes. Working closely with Martin Gamache, we created a base image, which in 2012 helped create the foundation for creating this poster. This giant climbing poster maps all of the routes on El Cap including the new Free Climb of the Dawn Wall by Tommy Caldwell and Kevin Jorgeson.

Thanks to Jimmy Chin, I received a call from National Geographic. Their goal was to expand the composite drawing of the Southeast Select across the entire face. Again Tom Frost's never ending support kept me moving forward and in the end my artwork was shared with 8.3 million people in 36 languages.

A year later, using the National Geographic base images and expanding them around the corner to include the West Face, I created the ultimate base image of every feature on El Capitan. A lot had happened in Yosemite National Park in the decade since I drew the Southeast Select poster, and I was able to research and draw topos for 20 free climbing routes on El Capitan.

Another amazing asset was the Yosemite Extreme Pano Imaging Project by xRez Studio. This website brought a telescope right onto my computer screen where climbers like Tommy Caldwell could sit next to me and point out beta in amazing detail. The poster chronicles the evolution of the wall's free climbing routes and includes the underlying matrix of the wall's aid routes for reference.
